Characterization of RF–DC Transfer Difference for Thermal Voltage Converters With Built-in Tees in the Frequency Range 1 MHz to 1 GHz

We describe the construction of thermal voltage converters (TVCs) with built-in tees and the characterization of their RF-dc differences in terms of power and impedance using thermistor mounts at frequencies greater than 100 MHz and in terms of conventional TVCs at lower frequencies. We also present a description of the measurement system and an uncertainty analysis
